EYEGLASS Ann srncreo'nn FRAME.

Application filed. August is. 1924. Serial No. 732,402.

The invention relates to eye-glass and Spectacle frames which are constructed of non-metal material such as Zylonite or celluloid. More particularly and specifically th invention relates to reinforcing means employed in connection with the bridge and the connection between the same and the rims for holding the lenses of eye-glasses or sp'ec tacle's. i I

One objection to eye-glass and spectacle frames constructed of zylonite Or equivalent materialhasbeen the large percentage of breakage of the bridge or of the connection between the bridge and the rims/ A further objection has been that in the use of eye-glasses or spectacles the bridge has gradually become distorted or displaced from its original shape and position with respect to the rims whereby the lenses are not held by the frames in proper position With respect to the eyes. i i

The. general object of the present invention therefore is to provide means whichnot only strengthens the brides of zylonite' frames but also strengthens the connection between the saicl'bridg'es and rims and which also prevents permanent relative displacement between the bridge and the rims as a result of usage.

It is also an object of the invention to provide metallic means concealed within the bridge and having interlocking engagement withrims for the purpose hereinbefore indicated. v I

To these and other ends the invention comprehends the construction as hereinafter described in detail and as illustrated in the drawing, in which one convenient form of mechanical embodiment of the invention is depicted. However, it will be understood that changes in the details of construction may be madewithin the scope ofthe claims without departing from the principle of the invention. t y I In the drawing Fig. 1 a view showing a portion of eye'- glas's frame partly in section and partly in front elevation embodying the invention;

Fig. 10 is a similar view showing still another modification of the reinforcing metal member. J

Referring to the drawings, 1 and 2 designatethe rims of an eye-glass frame consisting of zyloniteor equivalent material. The inner peripheraledges of each of these rims is provided with a groove 3. Each of these grooves: is providedwith a deepened or depressed portions at the inner edges of the rims, which deepened portion extend in opv posite' directions upon the opposite sides of the points of connection with the opposite ends of the bridge to the rims.

In the several forms of construction the bridge comprises a portion 10 of Zylonite or equivalent material, the opposite ends of which are connected to the opposing inner edges of the rims 1 and 2 of the frame. The

connection of the opposite ends of the p ortion 10 to the rims is effected by cementing or inany known preferred manner.

In the construction as disclosed in Figs. 1 to inclusive, the bridge also comprises as reinforcing and strengthening means a couple of wires 11 and 12 which extend longitudinally through the bridge and through openings 13 and 14: in the rims 1 and 2.
